Comparison of treatment methods of primary obstructive megaureter

BACKGROUND: Primary megaureter (PM) is a common congenital uropathy. In this study, we compared the results of treatment options for primary megaureter with obstruction in UVJ. METHODS: The files of all patients who underwent open surgery and had a double J (JJ) ureteral stent for treating primary obstructive megaureter in our institution between 2010 and 2023 were evaluated retrospectively. The demographic information of the patients, the results of imaging tests before and after the surgery, early and late complications after the treatment, and the length of stay in the hospital were recorded. The results of both treatment methods were compared statistically. RESULTS: A total of 23 patients and 26 kidney units over 13 years were retrospectively analyzed. Eighteen patients were male (78%); 5 were girls (22%). Ureteral tapering and ureteroneocystostomy (UNC) were performed with open surgery in 8 patients, while JJ stent was placed in 12 patients primarily by cystoscopy. In the urinary system ultrasonography (USS) performed at an average of 3 months after the treatment, hydronephrosis grades were observed to regress in 25 units. All patients recovered after surgery and there was no significant difference between the two treatment methods (p> 0.05). CONCLUSION: In the treatment of primary obstructive megaureter (POM), endoscopic JJ stenting is as effective as ureteral reimplantation with open surgery. It may be considered more valuable due to the shorter hospital stay
